Brief Description

Delf.AHS is a backdoor that allows hackers to gain remote access to the affected computer in order to carry out actions that compromise user confidentiality and impede the tasks performed on the computer.

It captures certain information entered or saved by the user, with the corresponding threat to privacy:
passwords saved by certain Windows services; email addresses.

It sends the gathered information to a remote user by any available means: email, FTP, etc.

It causes information loss:
it indiscriminately deletes random files.

It reduces the security level of the computer:
it notifies the attacker that the computer has been compromised and is ready to be used maliciously.

Delf.AHS does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
